Download and install JDK OpenJDK 9 or later to use as the boot JDK to build and test OpenJFX. We recommend either JDK 910.0.1or a recent JDK 10 Early Access build.

Mercurial

OpenJFX, as with OpenJDK, uses Mercurial as the source control system. You must install some support for using Mercurial. Many (if not all) IDEs include built in support, although the tooling is generally not as good as you might get from a standalone tool.

Gradle is the primary build tool for building OpenJFX. We currently use Gradle 4.36for jfx-dev (IMPORTANT: Only this version is regularly tested).
